This belt drive kit replaces the factory drive gears and provides a quiet running and less fragile spindle for your mini-mill. The mill's spindle noise has been measured at 92db with the factory equipped gear drive and dropped to 66db with the Steele Company, LLC's belt drive kit installed both running at approximately 1000 RPM. It takes only 15 to 20 minutes for the bolt on installation of the kit on a mini-mill and requires no drilling or cutting modifications to the mill. The kit includes all needed hardware for the installation. The kit expands the speed ranges of the mini-mill from 0 to 1100 RPM in low range to 0 to 1700 RPM, and changes the high range's speed from 0 to 2500 up to 0 to 4300 RPM. This will allow most drilling, milling and boring to be performed in the low range. The new high range will allow milling with very small diameter end mills, burrs or engraving tool bits.
The kits are $145.00
